MacRabbit is a new CSS editor for the Mac. I haven’t had a go with it yet, but the extraction feature alone, which allows you to suck down the CSS for an arbitrary site using a custom user agent string so you can ‘spoof’ different browsers and circumvent browser-sniffing, looks like it might be worth a shot.

Update: Alert reader Joe Lewis notes that the program itself is called ‘CSSEdit’. ‘MacRabbit’ is the company that develops it. Joe also gives the program a glowing review, saying he’s been a happily-licensed user for several months already.
